Intermittent paint spraying system using regenerative combustion method

Abstract

The present invention relates to the fact that the painting and drying performed by separate systems in the past can be performed together in one system, and the harmful substances generated when painting are not removed by filtering and filtering devices using activated carbon or catalysts, but are carried out by burning The intermittent painting system using regenerative combustion to minimize the concentration of harmful substances in the exhaust gas. The above structure includes: an air supply chamber, a new gas supply pipe provided with a valve A, and a new gas inhalation chamber. The suction port is connected to form a filter and an air supply fan inside; the paint spraying room is connected to the air supply fan of the above air supply chamber through the air supply pipe, and is connected to the above new air supply through the exhaust pipe provided with valve B. The air supply chamber on the other side of the pipe is connected to form an exhaust filter; the regenerative combustion equipment, through the exhaust pipe, the distribution chamber is connected to the exhaust filter of the above-mentioned spraying room, and the above-mentioned exhaust pipe is set Air supply fan B, the distribution chamber on the other side of the exhaust pipe is connected with the air supply chamber through the processing gas circulation pipe, and a valve C is installed in the above processing gas circulation pipe; and the processing gas discharge pipe is connected from the above regenerative combustion equipment The front side of the valve C handles the separation of the gas circulation pipe and is provided with a valve D.

Description

technical field [0001] The present invention relates to an intermittent paint spraying system utilizing a regenerative combustion method. More specifically, it relates to the fact that the paint spraying and drying performed by separate systems in the past can be performed together in one system, and are not removed by filtration and filtration devices using activated carbon or catalysts. It is an intermittent painting system that utilizes a thermal storage combustion method that minimizes the concentration of harmful substances in the exhaust gas by burning harmful substances that are generated during painting. Background technique [0002] Generally, a paint booth is formed by a system that sprays paint on a product to be painted by spraying, and supplies hot air of an appropriate temperature to the interior of the paint booth to dry the painted product. Explain how this spray booth works as follows. If the product is put into the spray booth, the spraying operation is ca...

[0005] On the other hand, the filtration device or filter device used in the conventional painting booth mainly uses activated carbon or a catalyst to remove pollutants contained in the air and gas. At this time, the dust and pollutants generated when painting are Adhering to the filter and accumulating, as a result, the filter will be clogged, and the filtering function will be lost, and the high concentration of harmful substances in the atmosphere will be discharged, resulting in serious environmental pollution. It is necessary to alternately filter and filter periodically device and high-priced catalyst device, the economy will be reduced
